Nathan commented on HBASE-14442:
--------------------------------
Hi [~ndimiduk], I just thought I cloud build a scan with the same ^stopRow^
and ^startRow^, as the *TableMapReduceUtil* doesn't provide any interface for
^Get^ or ^GetList^, then the ^Scan^ API provides a constructor ^Scan(Get
get)^, a method ^isGetScan()^, also I find some description in the sources
{quote}
/**
* Create a Scan operation for the range of rows specified.
* @param startRow row to start scanner at or after (inclusive)
* @param stopRow row to stop scanner before (exclusive)
*/
public Scan(byte [] startRow, byte [] stopRow) {{
this.startRow = startRow;
this.stopRow = stopRow;
//if the startRow and stopRow both are empty, it is not a Get
*this.getScan = isStartRowAndEqualsStopRow();*
}}

get)

Thanks, maybe appending a ^0^ to the ^stopRow^ can solve my problem.

> Project: HBase
> Issue Type: Bug
> Components: mapreduce
> Affects Versions: 1.1.2
> Reporter: Nathan
> Assignee: Nathan
> Original Estimate: 0.5h
> Remaining Estimate: 0.5h
>
> I created a Scan whose startRow and stopRow are the same with a region's
> startRow, then I found no map was built.
> The following is the source code of this condtion:
> (startRow.length == 0 || keys.getSecond()[i].length == 0 ||
> Bytes.compareTo(startRow, keys.getSecond()[i]) < 0) &&
> (stopRow.length == 0 || Bytes.compareTo(stopRow,
> keys.getFirst()[i]) > 0)
> I think a "=" should be added.
